The XPG RAM shows extremely slow response times.
The XPG RAM shows extremely slow response times.
Hello everyone, I just upgraded my RAM from a single 16GB DDR4 XPG D30 to a dual channel setup using the same brand, speed, and timing. The dual channel is performing well, similar to the graded frequency setup. However, I'm encountering an issue: the timings are set to 20 22 22 instead of the required 16 20 20. When I attempt to adjust them, I get a blue screen even when using Ryzen Calculator. Is there something wrong with the BIOS? Thanks!
Have you ensured the BIOS is current, as staying updated benefits performance? Also, have you reviewed the QVL for your motherboard—perhaps the RAM isn’t fully confirmed. I own a 4x4 XPG RAM setup, which tends to be more affordable and works well with Ryzen. It’s now functioning smoothly on my 5960x, but it struggled to reach the rated 2666 MHz on my Ryzen 1700 system with an x370 motherboard.
This board is also a T-type, designed for up to 3600 MHz maximum. Even if you keep it under that limit, using a 2x16 Gb drive is not recommended. Many users with the same model face similar issues when trying to boost RAM speeds: https://www.techpowerup.com/forums/threa...gy.257363/.
According to AMD’s official data, it follows a T topology and supports only 4x8 Gb modules. Running 2x16 Gb sticks causes significant problems. 'If you’re seeking a non-T topology—also known as a daisy chain board—this is crucial information when choosing a motherboard for memory overclocking, especially with 16 Gb+ drives,' explains the source.
It’s important to note that T topology isn’t suited for high-speed RAM beyond 4x8 Gb, and using 16 Gb modules leads to poor performance and frequent crashes. The issue isn’t just about speed—it affects stability and reliability.
Manufacturers often mislead buyers by claiming higher speeds than what the board actually supports. Some boards with limited slots hide extra slots or have hidden issues, making them unreliable for overclocking.
For better results, consider switching to 8 Gb modules or a T topology board. If you stick with your current setup, it’s best to avoid 16 Gb modules and higher frequencies. On the Z390 platform, even though you managed to run 2x16 Gb at 1.45V, achieving stable speeds required higher timings (like 4133 MHz) compared to what you expected.
That's a great response! It's cool you upgraded recently. I remember when I last built a rig, I used an DDR3 Asus Maximus Hero and didn't have as many RAM options. I also accidentally ordered a 16GB stick by mistake during the process. Looking back, it seems I'm pretty fortunate the RAM is working well—3200MHz with 1.35 auto and 20-22 MHz. I think I'll stick to upgrading the CPU from my 2700X to something higher like a 3700 or better. Thanks a lot!
Yea, no one knows about this kind of stuff until it happens to you and then you look it up. I had the same ram on 3 motherboards hence I realised the motherboard was the problem (two boards refunded first with different problems, third one finally works!). Initially you can get inundated with 'user error / you dont know how to overclock ram / no one else has this problem' both from people who equally don't know anything about it and if trying to get help from the retailer. Fortunately I have until June 30th to return my gigabtye board for a full refund, will do that early next week.
